Abstract

In his comments on our previous article, Hinton-Bayre advocates the use of the regression based approach in most cases of determining reliable change. This article comments on Hinton-Bayre’s argument, discusses cases where the regression method might not be the preferred method, and presents adjustments that make the method more generally preferable.
